Even though 0.1 BTC isn't that much, I would totally recommend against this. 99% of all Altcoins are pure scams and are constructed to rip people off. Even if it works out nicely once or twice, at some point, it'll work out for the other party involved and you get rid of your precious Bitcoin.
I fell prey to cloak, back in the days. I won't blame Bobsurplus - the only reason I failed was because I got greedy. Got decent returns in the first run and I thought "hell, I can repeat this easily", and then, the price fell and fell, and Alty visited the thread less and less often to update people, who got more and more delusional.

If you care to keep your BTC and maybe increase it, I'd stay away from Altcoins as far as possible. What do you think why scammers create them over and over? Because it makes good money for the users? Hell, no.
